Abstract
An eyewear device that adjusts aspects of a displayed object as a function of a user's eyeglass prescription. A detector identifies object edges for displayed far objects. A correction chart stores brightness corrections as a function of eyeglass prescriptions. The object edges are brightened as a function of the brightness corrections to sharpen objects displayed for a user with nearsightedness and/or farsightedness.
